Managing Additional User Accounts

Hello, for my Lanka Tour Experience site, I need to create a login page reserved for tour operators.
The site has its login and signup for customers.

For tour operators, I have to create reserved pages (where customers cannot have Access)

I created the registration page using UM. https://prnt.sc/sdl6u3

when click on the travel agent link enters the login and registration page directly. https://lankatourexperience.com/travel-agent/

As you can see, registered agents can log in, or new agents can register.

once logged the agent redirects directly to the reserved page,
it’s this one! https://lankatourexperience.com/travel-agency-customize-further/
Everything is fine so far

The issue is if I use a customer’s credentials, it also works on UM login so; the customers can use their credentials to see tour operators reserved pages.
If you want to try, you can use below customer credentials.

How can I make UM login work only for the tour operators credentials? Is it possible to Give Access only for who registered on the tour agent page?

Another issue is after logging in using customer credentials; the registration form is hidden does not display.

Thanks in advance
Kalum
